Create an account (e.g. max.mustermann) in the Gerrit instance you want to crawl (e.g. review.typo3.org:29418), add your SSH public key to the Gerrit instance and execute the gerrie:check command to check your environment:

$ ./gerrie gerrie:check --config-file="./Config.yml"

Note

Important:
If your SSH key is protected by a passphrase this check will ask you to enter your passphrase to use the private key for this connection.
Gerrie does not save or transfer this passphrase to any foreign server.
The private key is only necessary to authenticate against the Gerrit instance.
